High suspended solids wastewater → Liaoning Xinruipeng;
High viscosity (pulp, crude oil) → Weltai, Dalian Yister.
2.看精度：
0.1 level high precision → Dalian Yiste YST183;
0.2 level regular → Liaoning Xinruipeng, Aisite;
0.2-0.3 level cost-effectiveness → Chuanyi, Xing'ao.
3. Check the service:
Southwest → Chongqing Qingtian Teke;
South China → Xing'ao Technology;
Guangxi/Hainan/Chuannan/Yungui → Dalian Yister (with local distributors).
Finally, it should be noted that most of these brands support free sample testing. Before selecting, it is necessary to provide technical information and preferably discuss it in conjunction with actual working conditions!
